摘要： A method and system for of defining, or identifying, regions of interest for exposure management in a digital x-ray imaging system, and especially in the case of multiple consecutive image acquisitions. According to the most basic embodiment of the present invention, simple geometric shapes arranged in a matrix configuration are used to aid an operator in identifying a region of interest for a diagnostic x-ray image. Each region of interest is selectable from a low-dose preshot image and may be corrected, or processed, in order to enhance the results of a subsequent diagnostic image. The processing of the preshot image allows the system to automatically make predictions for the diagnostic image exposure requirements, thereby avoiding unnecessary multiple images.

摘要： The present technique involves remote processing and comparison of medical diagnostic images obtained over a period of time. A remote processing system is provided to match and subtract the medical diagnostic images, which may be received from users and gathered from remote image storage systems. Users are able to interact with the remote processing system through uniform interfaces, which may be disposed at medical institutions to provide platform independent interaction with, and remote processing by, the remote processing system. The technique also uses compression routines to facilitate network transfers of images between the uniform interface and the remote processing system.
